" 0 onaiai (ti/56227141 42 A'TTORNEY Patented Dec. 16, 1941 UNITED. STATES PATENT OFFICE Donald 0. Hardie, Easton; Pa. Application September 12, 1939, Serial No. 294,548

7 Claims.

My invention relates to Spinning machines or -twisters and more particularly to improvements in fastenings for spring tension devices and thread guides which are mounted on the girt rail of such machines such as is shown and described in my prior Patent Number 2,199,591, dated May '7, 1940.

Thi improvement comprises a particular fastening means for a thread guide or for a ten-' sion device whereby the same may be changed from one for imparting a right twist to the thread to one for imparting a left twist with great facility and speed and thereby save a great deal of time.

The main object of the invention is to provide a spring appliance such as a tension device or thread guide and so formed that its endsare bent so that they will fit or snap within holes provided in the girt rail, or in a specially designed holder or adapter fastened to the girt rail.

A further object is to provide a simple and efficient snap-on spring appliance formed of a single wire.

Other objects and advantages will be disclosed during the course of the following description.

In the accompanying drawing-' Figure 1 represents a perspective of a portion of a thread spinning machine equipped with a thread guide embodying the present invention.

Figure 2 is a side elevation showing a thread guide mounted in place in the holder on the supporting girt rail.

Figure 3 is a top plan view of the thread guide and holder mounted on the girt rail.

Figure 4 is a view taken on the line 4-4 of Figure 2, a portion of the holder being cut away for the sake of clearness.

Figure 5 is a perspective View of my improved spring thread guide.

Figure 6 is a perspective view of the holder.

Figure 7 is a side elevation showing my device mounted in place on an inverted girt rail, and

Figure 8 is a View similar to Figure '7 but showing a basket tension wire applied to the girt rail.

Referring specifically to the drawing the machine is generally indicated at A and is provided with a girt or tension device supporting rail 9 which has attached thereto the thread guide ID with the yarn passing from a supply spool II through the thread guide to the take-up bobbin The thread guide as shown in Figure 5 comto form an eye I2, a vertical-post I3 and upper and lower arms I4 and I5, respectively.

The upper arm I4 is noted as being at a right angle to the arm I5 and is bent downwardly at 5 I6.

The girt rail or tension and guide supporting rail comprises an angle iron attached to the machineto form an upper or top side I! and a front side I8.

The invention further includes a novel holder or bracket I 9, as clearly shown in Figure 6, which is provided with holes whereby it is fastened on the front side of the girt rail by screws 2| or other suitable fastening means. This holder is provided with an enlarged thickened T-shaped portion 22. Holes 23 and 24 are vertically bored about one quarter of an inch deep in the top of this T-shaped enlarged portion and another hole 25 is horizontally bored about one quarter of an inch deep near the bottom thereof.

The holes or bores 23 and 24 provide for mounting thread guides having arms I4 bent either to the right (as shown) or to the left or to accommodate like forms of the baskettype of tension wire as shown in Figure 8.

In the modification shown in Figure '7, the holder I9 is dispensed with since the girt rail 9 is inverted and of a reversed L-shaped design forming the front wall 26 and the base 21. Holes similar to the showing in the holder in Figure 6 are bored in the top of the rail as at 28 and also at 29. The top holes are vertically bored about one quarter of an inch deep and the lower one horizontally about the same depth.

Figure 8 is similar to Figure 7 but shows a basket tension device 30 having the same type of fastening means applied to the inverted-girt rail. It is to be understood, however, that this tension device is equally effective when used with the holder I9 in Figure 6. Two vertically bored holes about one quarter of an inch deep are bored in the girt rail to accommodate right and left hand baskets, the use of which is well known in this art. This tension device 30 comprises a single piece of wire bent to form a coil 3|, a vertical post 32 and upper and lower arms 33 and 34, respectively. The upper arm 33 is bent downwardly at 35 for engagement with a vertically arranged hole.

In order toattach the device to the supporting rail the end I5 (Fig. 7) is first inserted in the hole 29. Then the part I6 of the arm I4 is inserted in the hole 28. The same principle is followed in Figure 8, and also when used with prises a single wire bent and doubled upon itself the holder in Fig. 6. It will be noted that the removal of the guide.

removing principle is used with the tension basket hole 25 in Fig. 6 is offset or centered below and between the holes 23 or 24. The same is true of the holes bored in the girt rail.

Since the portion I4 is at a right angle it naturally follows that the same will normally be parallel or flat against the holder or girt rail. Therefore to insert the part It in its hole slight pressure is necessary to force the part back so as to fit in th hole. The device has a certain amount of give whereby it may be raised slightly and seated at the same time. It is to be further pointed out that the vertical post 13 serves as a stop or backing when the post l5 enters its seat as shown in Figure 2.

It will thus be seen thatthe' thread guide upon being so inserted is firmly secured in place and will not swing sidewise or work loose. When the operator wishes to remove the same all that is required is to insert the finger between the parts l6 and i3 and by a slight upwardly and outwardly .pull release the same from its seat.

Such releasing allows the part M to be restored toits normal position and the devic may then be easily removed from the holder by simply withdrawing the arm from its seat 25, Figure 6, or seat 29, Figure '7.

A recess or cut-out portion 36 is provided in the holder so as to provide ample space for the finger to enter between parts l3 and Hi'for The same attaching and shown in Figure 8.

The holder or adapter l9 and the novel spring fastening means for the tension device and thread guide provide an efficient, cheap and expedient attaching means for devices of the type described.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred .embodiment of the same and that various changes inth shape, size and arrangement of parts may be resorted to without departing'from the spirit of my invention and the scope of the subjoined claims.

Having thus described my invention what I claim is:

l. A thread guide for a girt raiLsaid girt rail including a portion having at least two sockets formed therein at substantially right angles to each other, said guide comprising a single wire doubled upon itself to provide a bight portion and legs having free ends, said bight portion being looped on itself to provide a thread guiding eye, the .free end of one of said legs being adapted to be readily removably seated in one of said sockets, the free end of said other leg being adapted to be readily removably seated in the other of said sockets.

2. The structure of claim 1, the said last named leg, including a portion extending at substantially right angles to said first leg, said last named leg portion being adapted to engage said girt rail portion to limit the insertion of the free end of said first leg in said first socket.

The structure of claim 1, said last named leg, including a portion extending at substantially right angles to said first leg, said last named leg portion being adapted to engage said girt rail portion to limit the insertion of the free end of said first leg in said first socket, and the free end of said second leg being adapted to be tensioned for insertion in said socket.

4. The structure of claim 1, said girt rail portion comprising a separate socket-providing member detachably secured to said girt rail, said last named leg including a portion extending at substantially right angles to said first leg and adapted to bear against one face of said socket providing member, a laterally directed extension of said last named leg portion adapted to. be swung along a second face portion of said socket providing member at right angles to said first face portion to seat said free end of said second leg in the second socket, and said second face portion of said socket-providing member being recessed to permit said laterally directed extension of said second leg to be readily gripped.
